Risk Assessment of GitHub Copilot

0xabad1dea, July 2021

this is a rough draft and may be updated with more examples

GitHub was kind enough to grant me swift access to the Copilot test phase despite me @'ing them several hundred times about ICE. I would like to examine it not in terms of productivity, but security. How risky is it to allow an AI to write some or all of your code?

Ultimately, a human being must take responsibility for every line of code that is committed. AI should not be used for "responsibility washing." However, Copilot is a tool, and workers need their tools to be reliable. A carpenter doesn't have to

// homerunner is Brad's shitty Docker wrapper after he got tired of running 
// HA nine-VM Kubernetes clusters. Earlier versions of this tried to use podman
// and fancy cloud-init and CNI stuff but then I decided to go to the other
// extreme and write something super specific to what I need and super dumb:
// run my containers from gcr.io, and use my home Ceph cluster for mounts/state.
//
// This primarily runs Home Assistant, HomeSeer, an MQTT server, and some cameras.
// And some omitted misc stuff.
